Full-Stack Engineer (startup generalist) About this role We are seeking a Full-Stack Software Engineer to strengthen our engineering team.

We are committed to building an inclusive and diverse team, and do not discriminate based upon race, color, ancestry, national origin, religion, sex, sexual orientation, age, gender identity, gender expression, disability, veteran status, or other legally protected characteristics.

In this role you will help design, build, and ship new functionality across our stack: From back-end services and cloud infrastructure to the applications our customers rely on inside recycling plants.This is a hands-on engineering role for someone who thinks end-to-end.

You will take on real engineering challenges: reasoning through the logic, drafting the architecture, deciding how a solution should be deployed and served, and then implementing it.

As a small, fast-moving startup, we need someone comfortable working across the full stack and able to own a challenge from idea to production, a true startup generalist.

Responsibilities • Take engineering challenges end-to-end - define the logic, draft the architecture, decide how the solution is deployed and served, and implement it. • Design, build, and deploy back-end services and APIs on Google Cloud, using Cloud Run, VMs and Firebase Functions. • Model, store, and serve data reliably with Firebase and NoSQL databases. • Write clean, maintainable Python across services and internal tooling. • Containerize and ship applications with Docker, using Git/GitHub for version control. • Contribute to front-end applications (React, and potentially Swift-iOS). • Maintain high standards for code quality, scalability, and reliability in production environments.

Requirements • A university degree in computer science, computer engineering, or related field. • Several years of software engineering experience across the stack. • Strong proficiency in Python and solid general software engineering fundamentals. • Proven ability to solve engineering challenges end-to-end, from logic and architecture through to deployment and serving. • Experience with cloud and serverless technologies (Google Cloud, Cloud Run, Firebase Functions). • Experience with NoSQL databases (Firebase). • Experience with Docker and Git/GitHub. • Comfortable working autonomously in a fast-paced startup environment with high ownership. • Strong communication and collaboration skills.

Nice to Have • Front-end development experience with React. • iOS development experience with Swift. • Experience with edge systems: Python on Linux, containerized deployments, and on-device trade-offs. • Familiarity with industrial, IoT, or real-time monitoring systems.
